.net - CannotResolveClassInfoException：无法解析类型的 ClassInfo

Question

我正在做一个项目，我想将代码从 17.2 版重构到 21.2 版

当我运行该项目时，我收到此错误：

CannotResolveClassInfoException：无法解析类型“[Main.Alpha.Module, Version=1.0.7961.26051, Culture=neutral, PublicKeyToken=null]Main.Alpha.Module.Models.Base.Interfaces.IBaseIdentificationCode”的 ClassInfo。

我该如何解决这个错误？

IBaseIdentificationCode：

[DefaultClassOptions]
[NavigationItem("Base")]
[XafDisplayName("IdentificationCode")]
[ImageName("BO_Sale_v92")]
public interface IBaseIdentificationCode
{
    string Name { get; set; }

    IdentificationCodeType IdentificationCodeType { get; set; }

    //[XafDisplayName("Mailing")]
    IBaseReceiveObject ReceiveObject { get; set; }

    [XafDisplayName("Mailing")]
    public Mailing Mailing { get; set; }
}

识别码：
